Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a chemical spraying tool for in-situ soil remediation. Background Technology

[0002] When performing in-situ soil remediation, it is necessary to turn the soil over, apply the pesticide, and then cover it with soil to increase the contact area between the contaminated soil and the pesticide, and to reduce the loss and volatilization of the pesticide. Currently, most methods involve turning the soil over first, then applying the pesticide, and finally covering it with soil. The operation process is complicated, labor-intensive, and there is also a gap period in the soil before the pesticide is covered with soil. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention proposes a lightweight tool for applying pesticides during in-situ soil remediation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spraying tool for in-situ soil remediation, characterized in that it includes a soil-turning plow, an mounting arm, and a nozzle. The soil-turning plow includes an arched plow plate and several plowshares located below the plow plate. The front end of the plow plate is narrower than the rear end, and the plowing height of the plow plate gradually increases from front to back. The plowshares are strips parallel to the plowing direction of the soil-turning plow. The nozzle's connector is fixed behind the mounting arm, and the nozzle's water outlet is located below the plow plate.

[0005] Furthermore, the plowshare is located in front of the water outlet of the nozzle.

[0006] Furthermore, the lower end of the plowshare extends beyond the plow plate.

[0007] The tilling plow is connected to a traction device via an installed arm. The traction device pulls the tilling plow straight to turn over the soil in the contaminated area. This soil turning differs from traditional farming tilling. It only creates a crack in the surface of the soil and forms an arched clearance area between the turned-up soil and the soil under the plow. The nozzle sprays the pesticide into this clearance area. As the tilling plow moves forward, the clearance area after the pesticide is sprayed is covered again by the turned-up soil. In this way, the pesticide can be immediately covered by the soil, and the tilling, pesticide spraying, and covering are completed in one step. In addition, in order to reduce the thickness of the turned-up soil and ensure that the pesticide can better penetrate into the soil, several plowshares are set under the plow plate. As the plow plate moves, the plowshares form strip-shaped grooves on the surface of the soil under the plow, which facilitates the storage of pesticide and increases the contact between the pesticide and the soil. The pesticide can better penetrate into the soil and is less likely to be squeezed out after covering. Attached Figure Description

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the device includes a soil-turning plow, a mounting arm 1, and a nozzle 2. The soil-turning plow includes an arched plow plate 3 and several plowing irons 4 located below the plow plate 3. The front end of the plow plate 3 is narrower than the rear end, and the plowing height of the plow plate 3 gradually increases from front to back. The plowing irons 4 are strips parallel to the plowing direction of the soil-turning plow. The nozzle 2's connector is fixed behind the mounting arm 1, and the water outlet of the nozzle 2 is located below the plow plate 3. The plowing irons 4 are located in front of the water outlet of the nozzle 2, and the lower end of the plowing irons 4 extends below the plow plate 3.

[0014] The tilling plow is connected to the traction device via the mounting arm 1. The traction device pulls the tilling plow straight to turn over the soil in the polluted area. This soil turning is different from traditional farming tilling. It only creates a crack in the surface of the soil and forms an arched clearance area between the turned-up soil and the soil under the plow. The nozzle 2 sprays the pesticide into this clearance area. As the tilling plow moves forward, the clearance area after the pesticide is sprayed is covered again by the turned-up soil. In this way, the pesticide can be immediately covered by the soil and the tilling, pesticide spraying and covering can be completed in one step. In addition, in order to reduce the thickness of the turned soil and ensure that the pesticide can better penetrate into the soil, several plow irons 4 are set under the plow plate 3. As the plow plate 3 moves, the plow irons 4 form strip-shaped grooves on the surface of the soil under the plow, which facilitates the storage of pesticide and increases the contact between the pesticide and the soil. The pesticide can better penetrate into the soil and is less likely to be squeezed out after covering.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
